Research on the Cutting Performance of Fine-grain Abrasive Stone

Abstract

In many cases, the cutting performance of the fine-grain abrasive stone is presumed by testing the bond hardness, but frequently we found different cutting performances for the abrasive stones of same bond hardness. In oder to test the cutting performance of abrasive stone, a special testing apparatus with which stone wear, stock removal and cutting force can be mearsured was designed. Then the testing results of cutting performance obtained with above testing apparatus was compared to the results of superfinishing performance with same abrasive stone under the most suitable working conditions, and it was clarified that this testing apparatus is effectually avaiable to investigate the cutting performance of the fine-grain abrasive stone.
